You couldn t change the enclave in fallout 2 or 3.
Fallout 4 siding with institute and railroad.
As simple as that.
They re looking to free synths not make a deal with the institute.
The railroad shows synths as regular humans wanting a better life.
I like the bos all morality etc and everything else aside they re the only group that you feel their presence in the commonwealth they actually show up and do things randomly in locations while the railroad sits in its tomb the institute sits in its bunker and the minutemen sit behind their castle walls.
Siding against the railroad means you d be picking up more reinforced railroad coats gauss rifles and raillway rifles.
It s a clear example of what a synth could be.
Siding with the minutemen.
While the institute shows you gabriel a synth whose memories were wiped who thinks he s human.
Gabriel ends up leading a raider band in libertalia and ends up killing innocents for gain.
The more quests the sole survivor does for the railroad the more the institute and the brotherhood of steel will disapprove of their actions.
Membership in the railroad may negatively affect relations with other main factions.
Telling the railroad about a compromise would go against everything they re fighting for.
I usually side against the institute no matter what so i may be biased.
Siding with institute turns ss into kellog 2 0.
Has you commit genocide against three groups including the ones they were formed to help leave the commonwealth without a faction to keep the raiders super mutants or gunners in check the institute did even if it was for self serving reasons.
For fallout 4 on the playstation 4 a gamefaqs message board topic titled siding with the railroad vs.
Personally i like the bos things a bit better but that might be a carryover from the original fallout and fallout 3.
